An image processing unit (IPU) may be used to process multiple streams of input/output (I/O) data transfers. For example, on a typical video use case there are more than 25 different streams alive as the IPU receives and/or transmits imaging data. An input/output memory management unit (IOMMU) is a memory management unit (MMU) may connect a direct-memory-access (DMA) capable I/O bus to the main memory. The IOMMU can map virtual addresses to physical addresses, and the IOMMU can also cache translation pages associated with a transition look-aside buffer identification (TLB_ID) via a set of transition look-aside buffers (TLBs).
